The tiles and edging is for a Christmas present so they haven’t been opened yet.
Potent Puck Stopper Edging (2-pack)
If you simply want it to prevent pucks from going off the end of the tile--it's perfect. Highly recommend.
Also, its much cheaper than the same piece bought for other tiles since they include the foam with the end piece for the one price.
Buuuut, I bought these hoping to use them as a passing aid. I have the passer but frankly it doesn't work great--it doesn't usually send pucks straight back, so I thought these might work since the Pure Hockey guys recommend them for other brands of tile (and I tried it in the store and it worked pretty well returning pucks from a passer). Anyway, the problem is if you pass into this foam it does come straight back--but after a couple of passes the puzzle piece starts to lift up and disconnect from the other tiles. So its not really a solution
